The Muncie A20-A1011-HX1CB or A20A1011HX1CB is a medium-duty, clutch shift power take-off from Muncie's A20 Series, designed specifically for Allison 3000 and 4000 Series automatic transmissions. The 10-bolt mounting pattern and extended-length PTO mounting fasteners simplify installation, while the shift cover allows full 360-degree rotation for flexible positioning. A rotatable pump flange and increased clearance reduce installation time on the chassis. Internally, tapered roller bearings extend service life, the clutch pack design carries a single intermittent/continuous torque rating, and the maximized gear geometry keeps noise down. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension. Call us to confirm the correct housing arrangement and output configuration for your application.
